1、LoadingBar的实现示例：

先导入需要的库文件：

#include "ui/UILoadingBar.h"

using namespace ui;

bool LoadingBarTest::init()

{

   Sprite* bg_sprite=Sprite::create("HpBar/sliderBg.png");

    bg_sprite->cocos2d::Node::setPosition(Point(200,200));

   this->addChild(bg_sprite);

    LoadingBar* loadingBar=LoadingBar::create("HpBar/sliderValue.png");

    loadingBar->setPosition(Point(200,200));

    loadingBar->setTag(0);

   this->addChild(loadingBar);

    scheduleUpdate();

    return true;

}
